16 Claims.

This invention relates to improvements. in shaving or hair clippingapparatus.

This is a continuation in part of my copending application Serial No.162,575, filed September 7, 1937, which matured into Letters Patent No.2,203,021 of June 4, 1940, and also relates to improvements in the hairclipping and shaving devices illustrated in my copending applicationsSerial No. 53,809, filed December 10, 1935, and Serial No. 134,439,filed April 1, 1937, which matured into Letters Patent No. 2,228,768 ofJanuary 14, 1941, and No. 2,203,020 of June 4', 1940, respectively,

The main objects of this invention are:

First, to provide an improved electrically actuated mechanical shavingor hair clipping device wherein the cutting head and cutter therein-maybe readily assembled for use and disassembled for cleaning. 7

Second, to provide a device of the type de-- scribed having a removablehead which is firmly held in operative position by a single retainingelement. I

Third, to provide a device of the character described, wherein the headand cutter slidable therein may be removed from the handle and likewiseseparated from each other for most effective cleaning or sterilizingthereof'and replaced in operative relation with a minimum of time andmanipulation, there being no possibility of assembling them in otherthan the proper operative relation.

Further objects relating to details and economies of my invention willdefinitely'appear from the description to follow. The invention isdefined in theclaims. p

A structure embodying the features of my inventionis illustrated in theaccompanying drawing, wherein:

Fig. 1 is a view in side elevation illustrating an electrically actuatedmechanical shaving orhair clipping device which is provided with theimprovements of my invention, illustrating details of constructioninvolved in those improvements.

Fig. 2 isan enlarged fragmentary view in vertic-a1 longitudinal sectionthrough the head portion of the device illustrated in'Fig. 1 and insection on line 2-2 of Fig, 3.

Fig. 3 is a fragmentary view in section on line 33 of Figs. 1 and 2.

Fig. 4 is a perspective View illustrating the securing or locking pinconstituting an element of the assembly of my invention.

' Fig. 5 is an exploded or separated view illustrating the manner inwhich the structure of my invention is disassembled for cleaning and thelike.

Fig. 6 is a fragmentary view in longitudinal vertical sectionillustrating a modified form of cutter head in aocordance'with myinvention.

Referring to Fig. 1, the reference numeral l indicates an electricallyactuated mechanical shaving or hair clipping device having a handle 2.This handle is of suitable size for gripping andhouses an electricactuating motor as is the common practice in devices of this type. Thehandle has at its outer, end a channel-like recess 3 (see Fig. 3)removably receiving the cutter head 4, This head is provided with achannel-like chamber 5 receiving and housing the cutter 6 forreciprocal, movement of the latter therein. The head is provided withopenings 1 adapted to be alined with corresponding openings 8 in thehandle through which rods 9 project to engage sockets [0 in the cutter.cutter is driven by the electric motor (not shown) in a conventionalmanner for reciprocation in the'head 4.

At each side, the head 4 has a curved portion ll merging into a cuttingface. I2 which has transverse slots 13 therein extending into the curvedportions. These slots provide a series of transverse combined guard andshear bars I 4 which coact with spaced cutter members 15 on cutter 6,the cutter members and shear bars being in sliding relation to effect ashearing action in a manner well known to the art.

In accordance with my invention, I provide end or guard members I6, I!for the cutter head 6, which are of channel section, preferably sheetmetal stamp-ings. 'These' end members have curved side portions. and endportions l8 complementing the curved side portions H of the head andmerging into the. curved side portions H of the head, also merging intothe flat top of the latter. with the head in a manner to be described sothat this merging relation of the curved surfaces is possible, with theresult that a cutting head having smoothly rounded sides and endsresults, permitting the same to be pressed very firmly against the skinwithout resulting in digging into or abrasion thereof, and on the wholegrea'tly improving the cutting action.

As illustrated in Fig. 2, the end members or guards. l6, I! are securedin operative relation to the razor structure in somewhat differentmanners. That is, the guard l6'is substantially longer than the guard l1and terminates in an The.

The end members are associatedoutwardly angled base or shank portion H)which is received in a correspondingly shaped recess in handle 2, beingsecured to the handle by a screw 20. On the other hand, the guard ll issecured directly to one end of the cutter head 4 by means of a screw 2|.

In order to secure the cutter head 4 to handle 2 in the channel 3 of thelatter, I utilize a tapered securing pin 22 which is illustrated per sein Fig. 4 and also in its coactive relation to the other parts in Figs.2 and 3. This pin is tapered from end to end and has a pair of parallelfiat sides which enable the same to be non-rotatably engaged with alinedholes 23 (of similar fiat sided configuration, but of difierent size) inthe handle at opposite sides of the :channel-like recess 3. The head hasa circular hole 24 extending therethrough and adapted to likewisereceive pin 22 to pin the head securely to the handle. It will be notedthat hole 24 is reduced in diameter approximately midway of the same toprovide a shoulder 25 against which the pin engages to exert wedgingretaining force on the head. By reason of the fact that the openings 23have the flat sides thereof inclined upwardly and to the right asclearly illustrated in Fig. 5, the tapered securing pin 22 urges thehead 4 downwards and also to the left, thereby effectively securing thesame in proper position on the bottom of the channel and snugly againstthe left guards 16 on the handle. The holes or openings 23, being ofdifferent size, render it impossible to successfully insert pin 22 fromthe wrong direction and provide that the upward fonce of reaction willbe efiectively taken by the handle at both sides of the head receivingchannel therein. This provides an effective clamping action and at thesame time the pin slips very freely into and out of position.

In order to retain the pin in position, I provide a turn button or clip26 (see Fig. 1) which is pivoted at 21 to be swung into and out ofengagement with a keeper 28. The clip has a seat 29 which snaps over theend of pin 22 to urge the same in its direction of engagement, asillustrated in Fig. 3.

The foregoing details of construction enable several decided advantagesto be attained. In the first place, in operative relation, the cutterhead is secured in snug displacement-resisting engagement with thehandle in its proper position against the left-hand guard I6. In thesecond place, with the guard 16 secured to the handle and the guard I?attached to the head, it is possible to remove the head and cutter inthe manner illustrated in Fig. without disturbing guard Hi. This permitsthe cutter to be readily withdrawn from within the head for cleaning orsterilizing and just as readily replaced in operative position for use.The tapered pin securing means automatically effects the properengagement of the head with the guard IE on the handle. There is aminimum of parts to be manipulated in the aforesaid taking down andreplacement and the whole assembly is a very inexpensive one.

Inasmuch as removal of the guard member H from the head 4 isunnecessary, it may be integrally and non-removably secured thereto, as11- lustrated in the modified embodiment of Fig. 6, wherein the guarddesignated 30 is spotwelded to the base 3| of the cutter head at 32 andalso at the point 33. It might even be practical to cast these partsintegrally or at least to produce all of the parts of the head save itsbase as a sheet metal stamping.

. I have illustrated and described my improvements in embodiments whichare very practical. I have not attempted to illustrate or describe otherembodiments or adaptations as it is believed this disclosure will enablethose skilled in the art to embody or adapt my improvements as may bedesired.
